^ MPRO'VED RAILROAD-SWITCH.

Be it known that I, MICHAEL KELLY, of St. Gnarles, inthe county of St.Charles, and State of Missouri, have made certain new and usefulImprovements in Railroad-Switches; and I do hereby declare that thefollowing is a full and clear description thereof, refer` ence being hadto the accompanying drawings, and

to the letters o'f reference marked thereon.

The obj ect of this invention is to construct a switch,

for railroad-purposes, which shall so 'guide the wheels passing over it-as to vprevent their leaving the rails, although the switch-railsshould not be setto those rails onryyhich tlenwhe'els may be travelling.

Itis obvious that in a switch so constructed, no displacement of theswitch will cause a train to be thrown from the track.

The invention consists of att-aching, tothe sides of the switch-rails,lugs, on which the iianges of Y the wheels will climb up and mount overthe rail, when it should be misplaced. It will be necessary, however, touse, in connection with this switch, wheels of a peculiar construction,having a central flange, and two equall or nearly equal faces or'treads. i

To enable those skilled in the art to make and use my improved switch, Iwill proceed to describe its construction and operation.

Figure 1 of the drawings is a plan of the improved 4 switch.

Figure 2 is a side elevation o the same.

The switch-rails A are coupled with the rails A of the main track, orwith therails B of the side track, in the'usual manner, and they may bethrown over, so as to couple. with either track, by means of the switch-"rods a c, in the usual manner. Attachedv to the outsides of theswitch-rails' :are lugs C C', the top faces of which present inclinedplanes, as shown in iig. 2.

In connection with this switch it will be necessary to use wheels havingcentral iianges, and two equal or nearlyv equal treads or faces, as isexhibited by the wheels D D'. The guard-rails E will be about the sameas those in common use by the sides of switch.- frogs, the ends of thembeing curvedslightly inward, to prevent the wheel-ang'es from strikingon the points of them.

The switch being constructed as above described, and the switch-railsbeing 'set to the side track, as exhibited in fig. 1, .and the wheels DD approaching the switch-rails, the 'iiange d, of the wheel D, lwillstrike on thelug C, ai'x'd run up on top of it, and so on over the topof the switch-rail, until the tread of the wheel drops down en .top ofthe rail again in its proper position. In approaching the ends of theswitch-rails, when they are thus misplaced, the inside tread of one oftheggwheels will run on the loutside of the switch-rail on one side, andthe inside tread of the other wheel on the guard-railE, until the properposition is attained.,-

Having described my invention,

What I claim, is The lugs C C and guard-rails E E, when arranged,relatively to each other, as set forth, in combination with switch-railsA, as shown; for the purpose exr plained.

In testimony of which invention, I hereunto set my hand in the presenceof` Witnesses:
